Subject: [PATCH net-next 4/5] bnx2x: Parity errors recovery for 578xx

Fix the parity errors recovery flow for 578xx:
    - Add a separate column for the 578xx in the parity mask
      registers DB.
    - Fix the bnx2x_process_kill_chip_reset() to handle the blocks
      newly introduced in the 578xx.

Cover ATC and PGLUE_B blocks for 57712 and 578xx.
